RT Journal Article T1 Observation of two-proton radioactivity of (19)Mg by tracking the decay products A1 Mukha, I. A1 Sümmerer, K. A1 Acosta Sánchez, Luis Armando A1 Álvarez, M. A. G. A1 García Ramos, José Enrique K1 Física nuclear AB We have observed the two-proton radioactivity of the previously unknown 19Mg ground-state bytracking the decay products in-°ight. For the ¯rst time, the trajectories of the 2p-decay products,17Ne+p+p, have been measured by using tracking micro-strip detectors which allowed to reconstructthe 2p-decay vertices and fragment correlations. The half-life of 19Mg deduced from the measuredvertex distribution is 4.0(15) ps in the system of 19Mg. The Q-value of the 2p-decay of the 19Mgground-state inferred from the measured p{p{17Ne correlations is 0.75(5) MeV.
